bindbidirectional vue js
To achieve bidirectional data binding in Vue.js, you can use the v-model
directive along with a computed property. Here are the steps to implement it:
Step 1: Create a data property in your Vue instance to store the value you want to bind bidirectionally. For example, let's say you want to bind an input field to a variable called message
:
data() {
return {
message: ''
}
}
Step 2: In your template, use the v-model
directive to bind the input field to the message
variable:
<input v-model="message" type="text">
Step 3: Create a computed property that returns the same value as the data property. This computed property will be used to update the data property when the input field changes:
computed: {
messageComputed: {
get() {
return this.message;
},
set(value) {
this.message = value;
}
}
}
Step 4: In the template, bind the computed property to the input field using the v-model
directive:
<input v-model="messageComputed" type="text">
Now, when you type in the input field, the message
data property will automatically update, and vice versa. This allows for bidirectional data binding in Vue.js.
